I sent an email to my old college (not DDs) raising concerns about the addition to the t&c’s and got this back.
“The text you mention was added to the University’s general ‘terms and conditions’ document this year, on legal advice following the rapidly changing admissions landscape during the 2020 exam results
This year we have already taken into account the fact that most UK pupils will not sit public exams as usual. As a result, we at (name of college)are confident that we will be able to admit all successful offer holders for the course and year stated in their offer.
Regarding the question of over-offering to fill places, I should mention that we do indeed try to make as many offers as possible, because we would find nothing more frustrating than rejecting applicants at the offer-making stage, only to discover that we have unfilled places by the start of the academic year. Conversely, our guarantee to house all freshers on our main site so they can be immersed in College life does set an absolute upper limit on numbers, so managing our intake numbers can be a difficult, but important, balancing act.
We also reassure all our offer holders that they are welcome to contact us if they have any concerns about their offer, and so far one has indeed contacted us about the clause in the T’s and C’s document. I have hopefully allayed their worries somewhat.”
Not sure if that helps reassure, but I hope so.
